The MeerKAT Fornax Survey. III. Ram-pressure stripping of the tidally interacting galaxy NGC 1427A in the Fornax cluster
P. Serra, T. A. Oosterloo, P. Kamphuis +16
We present MeerKAT Fornax Survey HI observations of NGC 1427A, a blue irregular galaxy with a stellar mass of 2e+9 Msun located near the centre of the Fornax galaxy cluster. Thanks…
Neutral atomic and molecular gas dynamics in the nearby spiral galaxies NGC 1512, NGC 4535, and NGC 7496
Sebastian Laudage, Cosima Eibensteiner, Frank Bigiel +20
Neutral atomic gas (HI) effectively traces galactic dynamics across mid to large galactocentric radii. However, its limitations in observing small-scale changes within the central…
PHANGS-MeerKAT and MHONGOOSE HI observations of nearby spiral galaxies: physical drivers of the molecular gas fraction,
Cosima Eibensteiner, Jiayi Sun, Frank Bigiel +36
The molecular-to-atomic gas ratio is crucial to the evolution of the interstellar medium in galaxies. We investigate the balance between the atomic () and molecular gas…
MHONGOOSE discovery of a gas-rich low-surface brightness galaxy in the Dorado Group
F. M. Maccagni, W. J. G. de Blok, P. E. Mancera Piña +28
We present the discovery of a low-mass gas-rich low-surface brightness galaxy in the Dorado Group, at a distance of 17.7 Mpc. Combining deep MeerKAT 21-cm observations from the Mee…
MHONGOOSE -- A MeerKAT Nearby Galaxy HI Survey
W. J. G. de Blok, J. Healy, F. M. Maccagni +57
The MHONGOOSE (MeerKAT HI Observations of Nearby Galactic Objects: Observing Southern Emitters) survey maps the distribution and kinematics of the neutral atomic hydrogen (HI) gas…
Possible origins of anomalous HI gas around MHONGOOSE galaxy, NGC 5068
J. Healy, W. J. G. de Blok, F. M. Maccagni +17
The existing reservoirs of neutral atomic hydrogen gas (HI) in galaxies are insufficient to have maintained the observed levels of star formation without some kind of replenish…
